Problems solved by technology

However, the active metal compound and aluminum hydroxide dry rubber powder or alumina powder are directly mixed and formed by kneading method. This method has problems such as uneven mixing of crystal particles and deterioration of catalyst strength. It is not easy to combine with each other to form a specific skeleton structure

Abstract

The invention provides a C5 petroleum resin hydrogenation method. The method includes: dissolving C5 petroleum resin into an organic solvent in a mixer, preheating, adding into a fixed bed hydrogenation reactor filled with a nickel-molybdenum hydrogenation catalyst, sending hydrogenated materials into a steam stripping tower, recycling the organic solvent extracted from the upper portion after refining the organic solvent through a distillation column, and obtaining C5 petroleum resin at the bottom of the steam stripping tower. By adoption of the catalyst prepared from a nickel-containing carrier in a specific crystal form, reactive metal utilization rate can be greatly improved, and catalyst preparation difficulty is lowered; in addition, due to adding of a selected active component, a synergistic effect is achieved, and C5 petroleum resin low in bromine number and high in chromaticity and stability can be obtained.

Description

technical field [0001] The invention relates to a method for hydrogenating C5 petroleum resin, in particular to a method for hydrogenating C5 petroleum resin catalyzed by a nickel-molybdenum series catalyst. Background technique [0002] The carbon five hydrocarbons mainly come from the by-product carbon five fractions in the high-temperature cracking of petroleum hydrocarbons to ethylene (referred to as cracked carbon five) and catalytic cracking gasoline in petroleum refineries. As of 2015, the global ethylene production capacity has reached 200 million tons. If liquid hydrocarbons (such as naphtha and light diesel oil) are used as cracking raw materials, the cracking C5 yield can reach 14-20% of the ethylene production. [0003] The utilization of carbon five hydrocarbons includes two aspects of fuel and chemical industry. For now, C5 hydrocarbons are basically used as fuel, and the chemical utilization rate is only about 10%. In terms of cracking C5 utilization, Shangh...
